Can't Stop Geeking

So for my work, I need to find a way to remotely repair PCs or somehow automated the process when I’m away and I need some advice.  I’ve posted the question over at Yahoo answers but if anyone can help me choose a solution here, that’d be great.  I found a PC repair solutions provider in the link, but I don’t know how well they scale, cost, etc.  Please email me with any suggestions, thanks so much!
